Dess-Martin periodinane (2.54 g, 5.98 mmol) was added to a solution of methyl 6-(hydroxymethyl)pyridine-3-carboxylate (Intermediate 190, 1.00 g, 5.98 mmol) in DCM (75 mL) at room temperature. The reaction mixture was stirred at room temperature for 24 hrs before being diluted with DCM (50 mL), washed with a 1:1 mixture of saturated aqueous solution of sodium bicarbonate and sodium thiosulfate (3×75 mL). The organic phase was dried over sodium sulfate, filtered and evaporated under vacuum to provide the title compound (1.02 g, 105%). Method B HPLC-MS: MH+ requires m/z=166 Found: m/z=166, Rt=1.44 min (62%).
